I have 12 Monitor setup that is run by three ATI FirePro 2460 GDDR3 512 MB cards.
Each card has 4 ports so each runs 4 monitors. I have been using this setup or last 5 years for displaying stock charts & using other regular applications including playing YouTube & regular videos. I DO NOT play any games at all.
I never had any problem with setup for last 5 years.
Recently one of the cards died so I bought a new one. But new one has identical specs except it has GDDR5 instead of GDDR3.
Now whenever I play YouTube videos, the new card crashes after few minutes. So 4 monitors that are connected to that video card goes blank & also keyboard & mouse freezes.
So I have to shut down the CPU using start button & Restart it & again all 12 monitors start working.
But then if I play YouTube videos, new card crashes after a while. Crashing time is random.
What seems to be a problem ? Is it because new card has GDDR5 instead of GDDR3 that other two cards have & thus it is not compatible with two other cards ? All cards are identical except the new one has GDDR5 instead of GDDR3.
